From 5cadd780883275cd7c1f968284e1a8cde4eb9426 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 27 Oct 2023 13:36:48 +0200 Subject: [PATCH] fbdev: stifb: Make the STI next font pointer a 32-bit signed offset commit 8a32aa17c1cd48df1ddaa78e45abcb8c7a2220d6 upstream. The pointer to the next STI font is actually a signed 32-bit offset. With this change the 64-bit kernel will correctly subract the (signed 32-bit) offset instead of adding a (unsigned 32-bit) offset. It has no effect on 32-bit kernels. This fixes the stifb driver with a 64-bit kernel on qemu.
